Equipment, Aids + Adaptations

I have noticed that many elderly people who are admitted to hospital with swollen lower limbs, red hot shiny lower limbs, lower limbs with oedema, both with and without cellulitis, happen to sleep in raiser recliner chairs or arm chairs. I am trying to find evidence or research to make an information sheet to advise patients that bed is best. It could be argued that the raiser recliner chair is not a reason for the patient to have the problem. It may be that the problem occurred first and the legs became so heavy and deconditioned that the patient finds it easier to get to sleep on the chair as they simply can no longer get onto the bed any more, therefore resorting to the chair.

I understand a slim repose mattress can be placed on the raiser recliner to reduce risk of pressure sores but its more that I would like to understand if the positioning of the patient in the chair, especially in heart failure patients or any cardio problem, exacerbates the oedema and cellullits directly though sleeping in a chair as apposed to a bed.
